Its been over a month since I last got my period and now am starting to worried. I am in my 20's and me and my boyfriend have been trying to have sex for a while now..I lost my virginity in October. This happened after my period that month. Middle of November I took the pregnancy test at home and again on the 30th and it said I am Not pregnant. But I am still worried now because its been over a month and no period. however, I recently got my signs i normally get when I am close to getting my period but the signs are gone and still I haven't got my period. Can someone please explain what might be my problem? thank you....
